Specification of Letters Patent.

Patented Aug. 8.

Application filed September 27, 1919. Serial No. 326,862.

To (IZZ 20710122. 27/ may concern Be it known that I, ALFRED E. BRUNS, acitizen of the United States, and resident of Brooklyn. in the county of l lingsand State of New York. have invented certain new and useful improvements in Containers, of which the following is a specification.

My invention relates tojcontainers and more particularly to tin or other metallic containers adapted to hold powder or'other similar substance.

The object of my invention is the. production of a novel inexpensive and simple form of metallic powder container, preferably sealed, having a construction enabling it to be loaded. or filled through the opening in which the sifter top is normally held. whereby said sifter top may be manually and tightly applied to the container after completion of the loading operation and whereby a removal of the sifter top to permit Lefllling of the container is rendered ex tremely diflicult if not impossible.

in the accompanying drawing illustrating a practical embodiment of-the invention:

Fig. 1 is a front elevation of a container embodying my invention.

Fig. 2 is a vertical cross-section on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal section through a portion of one of the walls of the container showing the annular opening or hole in which the sift-er top is mounted and held.

Fig. 4 is a front elevation of the sifter top.

Referring to the several figures of the drawing c 1. 1 indicate the side walls of a metallic container provided with flanges l 1 at the edges thereof and 2 indicates a side strip whose ends are joined together in any desirable manner (not shown) to make said side strip a continuous and endless one. Said side strip. at its edges, is provided with flanges 2 2 which lockingly engage the flanges 1 1 of the side walls, as clearly indicated in Fig. 2, the locking together of the flanges being effected by suitable rollers and producing a sealedv container. The side strip 2 is pro Vided with an annular opening or hole 3 having an upwardly extending shoulder 4 and an upwardly extending flange 5 forming a neckand flaring inwardly from and preferably integral with said shoulder 4 (see Fig.

6 indicates the head of my improved sifter top extending upwardly from the body of the container and which is provided with the usual perforations 7. ftlaid sifter top is adapted to receive the usual and ordinary form of slip cover or cap (not shown). Said sifter top is also provided with a downwardly depending, outwardly flaring flange or skirt 8 the inside diameter of the lower edge of which is of such size as to permit it to be readily slipped over the upper edge of the upwardly extending flange 5.

In the manufacture of the type of con tainer shown the side strip 2 is first punched with the opening or hole 3. the punching tool being preferably of a construction which permits the hole 3, shoulder 4 and flange 5 to be formed by one and the same operation. The side walls 1, 1 are then joined to the side strip 2 by the pressing together or interlocking of the flanges of said side walls and side strip by means of suitable rollers as previously described. t ainer which is then entirely closedv and sealed except for the'opening or hole 3may then be loaded with powder and the sifter top applied or locked thereto by slipping the edge of the flange or skirt 8 over the flange 5 and pressing downwardly on the Sifter top. The outside diameter of the flange 5 immediately adjacent the shoulder 4 is normally slightly greater than the inside diameter of the lower edge of the flange 8 and the inside diameter of the flange 8 at its top portion is slightly less than the outside diameter of the upper edge of the flange 5. When the sifter top, therefore, is pressed home or is pressed into the position shown in Fig. 2 with the free edge of the flange or skirt 8 engaging the shoulder 4, the flange 5 is compressed inwardly by the flange 8 thereby insuring an exceedingly tight frictional engagement between the two flanges throughout their lengths. The seat 4 not only acts to strengthen or reinforce the metal adja cent the opening or hole 3 but it also acts as a seat for the free edge of the flange or skirt 8. By this construction the sifter top is practically locked to thebody of the container so as to render the removal thereof for the purpose of refilling the container extremely difficult if not impossible.

In practice I have found my invention peculiarly applicable and valuable to containers of the type illustrated having beads adjacent the sifter top formed by the interlocked flanges of the side walls and side strip, for the reason that the sifter top can be applied or locked to the container after the body of the container has been menu factured to produce a sealed container 111-" In containers of capable of beingrefilled. 5 this class this heretofore usually has been impossible and it has been found necessary to provide the bottom of the side strip with. an additional hole for the insertion of a toolin order to turn over aTflangeof the sitter" top; as for instancefiange 8, and bring it into locking {engagement with the under side side strip, before the side walls were .joined to the side strip, for the reason that the sii'ter top would interfere with the action o lf the rollers for joining and interlocking together the flanges otlf the side strip and side walls.

,1 What I'claim asmy invention.is

container-having aflat side with a hole therein; annpwvarclly inwardly flaring and straight, flange integral' with said side and adjacent said-hole anda sitter top having an outwardly flaring straight fiangeengaging said inwardly flaring flange, ,the outside diameter t m lower end of said ,in- I said hole, an upwardly extending flan wardly flaring flange being slightly greater than the inner diameter of the sitter top flange at its lower edge andthe inside diameter of the upper portion of the sitter top flange being slightly less than the outside diameter of the upper edge of the flange adjacent the hole whereby whensaid flanges are pressed into engagement with each other the lower edge o'f'said sitter top flange will compress the other flange inwardly and a tight frictiona'land locking engagement between saidtwo flanges will be maintained throughout their lengths.

2. A container having a'iiat side with a single hole therein an'upwardly extending shoulder integral with said side and adjacent ge integral with said shoulder and flaring inwardly' therefrom and forming a neck and a perforated sitter top extending upwardly from said side and adapted to receive a cap and having an outwardly flaring flange frictional'ly and lockingly engaging the said neck and having its free lower edge tightly en aging the top of said shoulder;
